Akita folding fan shower curtain

The Akita family crest is said to have originated when Ando Sadatosi was summoned to Kyoto during the Kenkyu era (1190-1199) and received a beautiful Japanese cypress fan from Emperor Gotoba. At the time, a large eagle was presented from Goryeo (Korea), and the emperor gave two of its feathers to Sadatosi, placing them on the fan, saying 'For a warrior, what greater honor could there be?' This is recorded in 'Han Kan Fu' (a collection of feudal lord family chronicles from the early Edo period compiled by Arai Hakuseki). It is said that this became the Akita family crest of 'Cypress fan with eagle feathers'... (from 'The Family Crests of Daimyo Families' by Kenichi Takahashi). In 'Research on Definitive Crests' by Manjiro Fukui, this is referred to as 'Akita cypress fan with eagle feathers'.
